LINER FOR SANITARY SODA HOLDERS.

Application led January 3, 1921. Serial No. 434,446.

.To all whom it may concern Be it known that I, DAVID F. CURT'IN, a citizen of the United States, and a resident of the city of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements inl a Liner for Sanitary Soda Holders; and I do hereby de- A olare that the following is a full, clear, and

exact description of the same, reference being had to the accompanying drawings, and to the numerals of reference marked thereon, which form a part of this specification.

This invention relates to an improved liner for soda holders especially those of. interior conical form such as are shown and described in `Letters Patent to David F. Curtin, Nos. 1,139,018 and 1,303,171, patented on May 11th, 1915, and May 6th, 1919, respectively. It will also be understood that this liner is adapted to be used with any form of holder of similar conical shape on the interior thereof.

The chief object of this invention is the provision of a liner for sanitary soda holders which can be manually inserted therein' without any previous sha ing of the same into the form of a cup an which, when inserted, will be non-leakable.

A further object of the invention is the provision of a liner for sanitary soda holders which can be shipped to the consumer or dealer in av flat form and made into the shape of a cup by him at his convenience or whenever necessary.

Another important object of this invention is the provision of ain-improvedv liner for sanita soda holders which will provide a noneakable cup when inserted therein without the use of any adhesive and without any preliminary formation of the of the liner to tend to assume its original flat shape vor spring up out of the holder.

Other and further important objectsof the invention will be apparent from the dis- Closures in the drawings and annexed specifcation.

In the drawings: Figure 1 represents a blank from which the improved liner is made showing the position of the cup thereunder in dotted lines.

Figure 2- is a top view of the blank showing the same after it has been pushed partway into the cup.

Figure 3 is a side elevation showing the assembled holder and liner.

Figure 4 is a top plan view of the cup showing the liner in place therein.

Figures 5 and 6 are side and front elevations, respectively, of the shaped liner.

Figure 7 is an elevational detail of the latch. i

Figure 8 illustrates a storage holder containing a number of formed paper cups.

As shownon the drawings:

-The reference numeral 10 indicates a blank of approximately triangular shape having one of its edges or sides 11 in the form of an arc of a circle. The other two edges are shorter but of equal length to each other and are slightly concaveand they terminate in rounded projections or tabs 12 adjacent each other and separated merely by means of a slit .14 in the blank.

The termination ofthe slit 14 marks the exact centerv of the circle, one are of which forms the edge 11 of the blank .and this point forms the apex of the cup when the same is formed into a liner for a holder.

The blank is preferably made of paper, coated with parafiine or some other waterproofing-substance, and is manually inserted into the holder 16 which is preferably of the shape shown in Figure 3 but may be of any conical form and may even be in the form of an open dish like those ordinarily used to serve sundaes and the like.

In operation, in putting the liner into the holder the same is placed flat on the top edge of the cup in the position shown in Figure 1, the relation of the circular edge of the cup to the blank bein shown in the dotted lines with the end of t e slit 14 at the edge of the cup. The blank is then pushed down into' the cup by means of the ingers of the operator or by any convenient instrument, the end of the slit 14 being kept against the inside of the holder and the liner gradually assumes the shape shown in Figure 2. the two tabs 12 overlapping each other to form an apex at the termination of the slit 14. After the liner has been fully inserted into the cup and with its shape corresponding to the interior thereof it assumes the position shown in Figures 4, 5 and 6 in the escape of any liquid therethrou which position it is adapted to receive a soda or the like and will maintain the same in the holder without an possibility of leakage, the weight of the iquid bein sufficient to press the liner against the s1 es of the cup and to hold the overlapping edges together with sufficient pressure to prevent -h. '.lfhe apex of the cup is doubly protecte against leakage by means of the overlapping .tabs 12 which encircle each other for approximately two entire revolutions thereby forming a double reinforcement at the bottom point of the cup which would ordinarily be the part most likely to leak.

As the blank o-r liner is originally in a flat form there will be a tendency for the same, to reassume said flat form and' to spring upward out of the cup after having been pushed or positioned thereinto. lln order to prevent any such upward movement before the soda or liquid has been placed into the cup, a latch- 18 is provided preferably positioned in close relation to the handle of the cup as shown in Figure 3. rl'his latch is provided with any preferable adjustable retaining means 20, which may consist of a frictional binding screw entering aslot 21 in the latch member, and by slightly loosening the screw the latch can be slid up or down as is obvious.

lt will be obvious that the liner retaining means or latch 18 need not be ositio-ned adjacent the handle, but may, 1f desired, be attached at any point on the periphery of the rim of the cup. lin fact any holding means that will serve to retain the liner in adjusted position will suiiice. For example, a latch may be placed in the base vof the holder which is provided with an opening through which the apex of the liner extends said opening being primarily for the purpose of preventing any foreign matter from accumulating in the apex o-f the holder and thereby preventing the proper seating of the liner therein. Such a latch placed in the base of the holder and adapted to grip the protruding apex of the liner and retain it in position may in some cases be preferred, being entirely concealed from View.

lt will be evident that if a liner is inserted into a holder when required and a beverage immediately placed therein, the liner could and preferably would be held in position in the holder for a short time bv means of the thumb of the dispenser of the beverage. However, when a number of cups are to be filled at substantially the same time, the latches 18 constitute a valuable addition as they serve to retain the liners in position in the cups and hold the same ready for the dispensing of a. number of beverages.

The liners may be singly inserted into the holders as needed, or, if desired, a number of liners, approximately tive or six, may be inserted into one holder at the same time and formed roughly into shape. This may be repeated several times so that a number of liners according to the estimated re- 7 quirenients may be roughly shaped and ready in order to be quickly positioned into holders when needed. rlili-esel liners after being roughly shaped in the manner described may be stacked or nested in a storage holder 22 as shown in Figure 8, which may be similar to the ordinary paper cup holder,

and a conical weight 23 may be inserted in the upper portion of the holder to 'fully shape, expand and hold the same nested in expanded form.

lltwill be seen that herein is provided a liner for sanita-ry soda holders which can be used as readily as the prepare-d conical cups now o-n the market and which can be manufactured in greater quantities, and which moreover can be shipped in dat form, thereby effecting a saving of space and freight charges. 'lhepeculiar shape of this blank constitutes a very valuable feature inase" much as it has been found to be the most practical shape which will result in the formation of a conical liner which will be positively non-leakable when inserted into a. holder and filled with a beverage of any sort. llt will further be seen that there is no possibility of any puncturing of the liner as the same is at all times held securely against the interior of thecup which reinforces and protects the same from any accidental openings or punctures being made by spoons or the like.

ll ain aware that many changes may be made and the details of construction varied through a wide range without departing from the principles of this invention, and l therefore do not purpose limiting the patent granted hereon, otherwise than necessitated by the prior art.

ll claim as my invention:
